Shock absorbers transmit some of the shock directly to the isolated part. Engineers can mitigate the problem by adding dampers or with complex control systems, but the self-damped air spring offers a simpler option.
The self-damped air spring eliminates the need for shock absorbers in suspensions and vibration isolation systems.
Using a conventional air spring and a fixed-volume air chamber separated by an orifice, the design creates a force that is 180 degrees out of phase with the force-in function.
Isolation improves because the initial force from the input is absorbed totally by the spring with no damping. Damping occurs naturally and only when needed. Damping forces up to 30% of critical have been measured.

Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
